Muzzle Brake slop

[Stumpknocker]

Wasr 10 , added AK-74 type brake ran down to the furthest position that lock pin would hold and have measured 3/32 slop , I don't want to split lead at the brake, is that enough to cause it? I can tighten w/o using pin, just askin opinions from some old hands at it. BTW here's a pic of item

Thanks Guys
